empty method list
obtain like the fields :

var db1 = Java.use("your.class");
var methodArr = db1.class.getMethods();
for(var m in methodArr)
{
	console.log(methodArr[m]);
}

I've spent a lot of time to figure out how to get the fields which have the same name of methods. Can we put this in the document?

BTW, @douniwan5788 are you figuring it out by reading the source code?

Indeed there is one, this._m.value in https://github.com/frida/frida-website/blob/master/_docs/examples/android.md. While it's in Examples section instead of API Reference, I can't say it's well documented.
frida/frida#833 is also the same topic. Maybe a doc PR is needed.

@KANGOD Yes I added that one to the doc 😄

I think @0x410c meant to use "of" instead of "in".

for(var m of methodArr)

var m inreturns a list of indices instead of objects. Calling 0.class.getMethods() returns error: TypeError: cannot read property 'getMethods' of undefined
